Fig. 5. Mutations in the Drosophila lkb1 gene affect Mira localization at the NB basal pole. (A) Mira localization in wild-type, pins^P62/pins^P62 and dlkb1³¹⁵/dlkb1³¹⁵ NBs. Cells in metaphase and telophase were stained for tubulin (Tub), DNA and Mira. Scale bar: 5 µm. (B) Distribution of Mira in dividing NBs from wild-type (wt), dlkb1³¹⁵/dlkb1³¹⁵ and pins^P62/pins^P62 brains. Regular, regular Mira crescent at the basal pole; cortical, Mira associated with the entire cell cortex; diffuse, Mira dispersed in the cytoplasm.
